howler-gui 0.1.0

# Howler

A production-ready application for tracking and analyzing wolf (Canis lupus) sightings and movements across multiple data sources — with ML-powered behavior prediction.

## Features

- **Multi-Source Data Integration**: Fetch wolf sightings from GBIF, iNaturalist, IUCN, and Movebank
- **Advanced Analysis**: Pack territory detection (DBSCAN), movement analysis, and temporal pattern detection
- **Machine Learning**: Behavior prediction (stationary, territorial, linear, random, central-place), next-location forecasting, and activity pattern analysis
- **Interactive Maps**: Full map capabilities with OpenStreetMap tiles, zoom/pan controls, and multiple layers
- **Multiple Interfaces**: CLI, TUI (Terminal UI), GUI (Desktop), Web App, and Mobile App
- **Data Management**: Filter, search, export (CSV, GeoJSON, KML), and import wolf sighting data
- **Cross-Platform**: Runs on Linux, macOS, Windows, iOS, and Android

### From Source

```bash
git clone https://github.com/realgoldfang/howler.git
cd howler
cargo build --release
```

```bash
cargo install howler-cli
cargo install howler-tui
cargo install howler-gui
```

### Pre-built Binaries

Download pre-built binaries from the [Releases](https://github.com/realgoldfang/howler/releases) page.

## Quick Start

### CLI

```bash
# Fetch wolf sightings from all sources
howler-cli --fetch

# Generate a report
howler-cli --report

# Fetch from specific source
howler-cli --fetch --source gbif --limit 100

## Configuration

Howler uses environment variables for API key configuration:

```bash
# Movebank credentials (for GPS tracking data)
export MOVEBANK_USERNAME="your_username"
export MOVEBANK_PASSWORD="your_password"

# iNaturalist API token (optional — requires 5-month-old account with 10+ observations)
export INATURALIST_TOKEN="your_token"

# IUCN API token (optional — register at https://api.iucnredlist.org/users/sign_up)
export IUCN_TOKEN="your_token"
```

**All sources are optional.** Howler works without any API keys — it just uses GBIF (which is free and open).

### API Key Acquisition

**Movebank**:
1. Register at [movebank.org](https://www.movebank.org)
2. Create an account and request access to studies
3. Use your username and password

**iNaturalist**:
1. Register at [inaturalist.org](https://www.inaturalist.org)
2. Go to your account settings and create an API application
3. Copy the access token

**IUCN**:
1. Register at [api.iucnredlist.org](https://apiv3.iucnredlist.org)
2. Request an API token
3. Use the token in your environment

## Usage Examples

### Fetching Data

```bash
# Fetch from all sources
howler-cli --fetch

# Fetch specific number of sightings
howler-cli --fetch --limit 50

# Fetch from specific source
howler-cli --fetch --source gbif
```

### Exporting Data

```bash
# Export to CSV
howler-cli --export --format csv --output sightings.csv

# Export to GeoJSON
howler-cli --export --format geojson --output sightings.geojson

# Export to KML (Google Earth)
howler-cli --export --format kml --output sightings.kml
```

### Filtering Data

```bash
# Filter by date range
howler-cli --filter --start-date 2023-01-01 --end-date 2023-12-31

# Filter by source
howler-cli --filter --source gbif

# Filter by species
howler-cli --filter --species "Canis lupus"
```

## Machine Learning

Howler includes an ML module for wolf behavior prediction using random forest classification and linear regression.

### Behavior Classification

```rust
use howler_core::ml::{BehaviorModel, BehaviorFeatures, BehaviorType};

let model = BehaviorModel::new();
let features = BehaviorFeatures::from_sightings(&sightings);
let prediction = model.predict_behavior(&features);

match prediction.behavior_type {
    BehaviorType::Territorial => println!("Pack territory behavior"),
    BehaviorType::Linear => println!("Dispersal/migration pattern"),
    BehaviorType::CentralPlace => println!("Den-based activity"),
    // ...
}
```

### Next-Location Prediction

```rust
let location_pred = model.predict_next_location(&features);
println!(
    "Predicted: ({}, {}) in {} hours",
    location_pred.latitude, location_pred.longitude, location_pred.time_horizon_hours
);
```

### Supported Behavior Types

| Type | Description |
|------|-------------|
| `Stationary` | Wolf remains in small area (< 1km radius) |
| `Territorial` | Circular/area-restricted movement |
| `Linear` | Directed movement (dispersal/migration) |
| `Random` | No discernible pattern |
| `CentralPlace` | Activity centered on den site |
